is the oldest, most popular, non alcoholic caffeine containing beverage, in the
world. The presence of heavy metal even in trace amount causes adverse effect
both in quality and quantitative production. The accumulation of heavy metal
causes health issues also. In the present work we have studied the effect of chlorophyll
content which is an important photosynthetic parameter with the high
concentration of copper stress with respect to the days of the treatment in two
different cultivars viz. TV-23, TV-17
in hydroponically system. Both shoot and root weight decreased progressively
with increasing Cu concentration for Camellia
sinensis. Negative linear relationships were observed between total
Chlorophyll contents and Cu concentration. With the increase in the
concentration of Cu even at trace level causes deleterious effect in the
metabolism of plant especially photosynthetic activity which caused remarkable
breakdown in the photosynthetic parameters. A significant decrease of
chlorophyll started for both the cultivars was observed at concentrations above
300µM. From this study, we found the photosynthetic activity of TV-17 is more
sensitive to Cu stress than that of TV-23.
